Watch the "Movable Median Barrier" being repositioned by the amazing "Zipper Truck." A remarkable engineering feat, this system was deployed in January 2015 and can be seen here as it moves the barrier from camera left to camera right giving northbound traffic an extra lane of travel for commuters as they exit the city during the afternoon rush-hour. It’s all about safety and this system helps keep the northbound traffic departing the city separated from the southbound traffic heading into the city. Filmed in HD with the hopes it'll play in HD on your computer.
